Otherwise on (some) 64-bit systems, -Wformat will trigger a warning
because uint64_t is an 'unsigned long' not an 'unsigned long long'.
Consequently, PGOProfiling.c would fail to build if -Werror and
-Wformat are both enabled.

This is fairly minimal support for instrumentation based PGO. The data
format is inefficient, and the output file name is hardcoded to
pgo-data.

SymbolLookUp() call back to return a demangled C++ name to
be used as a comment.
For example darwin's otool(1) program the uses the llvm
disassembler now can produce disassembly like:
callq __ZNK4llvm6Target20createMCDisassemblerERKNS_15MCSubtargetInfoE ## llvm::Target::createMCDisassembler(llvm::MCSubtargetInfo const&) const
Also fix a bug in LLVMDisasmInstruction() that was not flushing
the raw_svector_ostream for the disassembled instruction string
before copying it to the output buffer that was causing truncation
of the output.

Now with a fix for PR18384: ValueHandleBase::ValueIsDeleted.
We need to invalidate SCEV's loop info when we delete a block, even if no values are hoisted.

Summary:
This parameter is required to build C++11 projects (like lld or lldb) on OS X as the default STL does not provide c++ classes.

The ARM backend has been using most of the MachO related subtarget
checks almost interchangeably, and since the only target it's had to
run on has been IOS (which is all three of MachO, Darwin and IOS) it's
worked out OK so far.
But we'd like to support embedded targets under the "*-*-none-macho"
triple, which means everything starts falling apart and inconsistent
behaviours emerge.
This patch should pick a reasonably sensible set of behaviours for the
new triple (and any others that come along, with luck). Some choices
were debatable (notably FP == r7 or r11), but we can revisit those
later when deficiencies become apparent.
llvm-svn: 198617
This requires a knowledge of the stack size which is not known until
the frame is complete, hence the need for the XCoreFTAOElim pass
which lowers the XCoreISD::FRAME_TO_ARGS_OFFSET instrution into its
final form.
llvm-svn: 198614
We also narrow the liveness of FP & LR during the prologue to
reflect the actual usage of the registers.
I have been unable to construct a test to prove the previous live
range was too large.
llvm-svn: 198611
This matches up the underlying type against the actual storage type 'unsigned
short' and lets us get rid of some casts while we're at it.
Effort is made to keep this building in pre-C++11 but as with other features
Token will be less efficiently packed in in legacy configurations.
llvm-svn: 198607
Implemented with a new getKeywordSpelling() accessor. Unlike getTokenName() the
result of this function is stable and may be used in diagnostic output.
Uses of this feature are split out into the subsequent commit.
llvm-svn: 198604
Longer term, we want to move users to "*-*-*-macho" for embedded work, but for
now people are relying on the last thing we told them, which is unfortunately
"*-*-darwin-eabi".

enum-scoped.cpp:93:6: error: enumeration redeclared with different underlying type 'short' (was 'int')
enum Redeclare6 : short;
^
enum-scoped.cpp:92:6: note: previous declaration is here
enum Redeclare6 : int;
^ ~~~
The redeclaration source range is still missing but this is a step forward,
potentially edging towards a FixIt.
llvm-svn: 198601
In all three checks, the note indicates a previous declaration and never a 'use'.
Before:
enum-scoped.cpp:92:6: note: previous use is here
enum Redeclare6 : int;
^
After:
enum-scoped.cpp:92:6: note: previous declaration is here
enum Redeclare6 : int;
^
